Corentin Labbe says: ==================== net: stmmac: misc fix I am currently working on dwmac-sun8i glue driver for Allwinner H3/A83T/A64. This series is the result of all minor problem found in the stmmac driver. All patch are tested on cubieboard2 via dwmac-sunxi and on pine64/orangepis via dwmac-sun8i. Changes since v1: - Removed netdev_dbg() in "net: stmmac: print phy information" - Removed patch "net: stmmac: Implement NAPI for TX", it will be reworked - Changed error message in "Correct the error message about invalid speed" - Added some acked-by ==================== Signed-off-by: David S.

2017-02-08bpf, lpm: fix overflows in trie_alloc checksDaniel Borkmann
Cap the maximum (total) value size and bail out if larger than KMALLOC_MAX_SIZE as otherwise it doesn't make any sense to proceed further, since we're guaranteed to fail to allocate elements anyway in lpm_trie_node_alloc(); likleyhood of failure is still high for large values, though, similarly as with htab case in non-prealloc. Next, make sure that cost vars are really u64 instead of size_t, so that we don't overflow on 32 bit and charge only tiny map.pages against memlock while allowing huge max_entries; cap also the max cost like we do with other map types.

2017-02-08arm64: uaccess: consistently check object sizesMark Rutland
Currently in arm64's copy_{to,from}_user, we only check the source/destination object size if access_ok() tells us the user access is permissible. However, in copy_from_user() we'll subsequently zero any remainder on the destination object. If we failed the access_ok() check, that applies to the whole object size, which we didn't check. To ensure that we catch that case, this patch hoists check_object_size() to the start of copy_from_user(), matching __copy_from_user() and __copy_to_user(). To make all of our uaccess copy primitives consistent, the same is done to copy_to_user().

2017-02-08packet: round up linear to header lenWillem de Bruijn
Link layer protocols may unconditionally pull headers, as Ethernet does in eth_type_trans. Ensure that the entire link layer header always lies in the skb linear segment. tpacket_snd has such a check. Extend this to packet_snd. Variable length link layer headers complicate the computation somewhat. Here skb->len may be smaller than dev->hard_header_len. Round up the linear length to be at least as long as the smallest of the two.

2017-02-08net: introduce device min_header_lenWillem de Bruijn
The stack must not pass packets to device drivers that are shorter than the minimum link layer header length. Previously, packet sockets would drop packets smaller than or equal to dev->hard_header_len, but this has false positives. Zero length payload is used over Ethernet. Other link layer protocols support variable length headers. Support for validation of these protocols removed the min length check for all protocols. Introduce an explicit dev->min_header_len parameter and drop all packets below this value. Initially, set it to non-zero only for Ethernet and loopback. Other protocols can follow in a patch to net-next.

2017-02-08regulator: core: simplify _regulator_get()Dmitry Torokhov
The code in _regulator_get() got a bit confusing over time, with control flow jumping to a label from couple of places. Let's untangle it a bit by doing the following: 1. Make handling of missing supplies and substituting them with dummy regulators more explicit: - check if we not have full constraints and refuse considering dummy regulators with appropriate message; - use "switch (get_type)" to handle different types of request explicitly as well. "Normal" requests will get dummies, exclusive will not and will notify user about that; optional will fail silently. 2. Stop jumping to a label in the middle of the function but instead have proper conditional flow. I believe jumps should be reserved for error handling, breaking from inner loop, or restarting a loop, but not for implementing normal conditional flow.

2017-02-08net: phy: Add LED mode driver for Microsemi PHYs.Raju Lakkaraju
LED Mode: Microsemi PHY support 2 LEDs (LED[0] and LED[1]) to display different status information that can be selected by setting LED mode. LED Mode parameter (vsc8531, led-0-mode) and (vsc8531, led-1-mode) get from Device Tree. Signed-off-by: Raju Lakkaraju <Raju.Lakkaraju@microsemi.com> Signed-off-by: David S.

2017-02-08USB: serial: metro-usb: drop redundant URB reinitialisationJohan Hovold
No need to reinitialise the interrupt-in URB with values that have not changed before (some) resubmissions. This also allows the interrupt-in callback to have a single path for URB resubmission.

2017-02-08net: dsa: bcm_sf2: cleanup bcm_sf2_cfp_rule_get() a littleDan Carpenter
This patch doesn't affect how the code works. My static checker complains that the mask and shift doesn't make sense because 0xffffff << 16 goes beyond the end of 32 bits. It should be 0xffff instead but the existing code won't cause runtime bugs. Also the casting here is not needed and not consistent with the rest of the code.
